If the moisture content of the paper and hydroscopicity, a business card printing and membership card making pressure that will have varying degrees of compression. 如果纸张的含水度及吸水性差别，在制卡和会员卡制作不不不抬力的功用下，会有差别水平的受不抬形变。
Experimental results showed that the treated fibers had much higher hydroscopicity than the untreated ones, due to the highly absorbent carboxymethyl groups in the fiber structure. 实验结果显示，由于处理后纤维的结构中含有高吸水性的羧甲基基团，处理后的纤维比初始纤维有更高的吸湿性。
